Glossary:
electronic tandem network (ETN)
A tandem tie-trunk network with automatic call-routing capabilities that are based on the dialed number and the most
preferred route that is available. Each switch in the network is assigned a unique private network office code (RNX), and
each telephone is assigned a unique extension. See also
Electronics Industries Association (EIA)
A trade association of the electronics industry that establishes electrical and functional standards for the member
companies.
emergency transfer
A mode of system operation in which, if a major system fails, automatic transfer is initiated to a group of telephones that
can make outgoing calls. The system operates in emergency transfer mode until the failure is repaired, and the system
automatically returns to normal operation. Also called power failure transfer.
EMI
See electromagnetic interference
EMS
See external media server
end-to-end signaling
The transmission of touchtone signals that is generated by dialing from a telephone to remote computer equipment. These
signals are sent over the trunk as Dual-Tone Multifrequency (DTMF) digits, whether the trunk signaling type is marked
as tone or rotary, and whether the originating station is tone or rotary. For example, with a call to a voice mail server or an
automated attendant service, a connection is first established over an outgoing trunk. Then additional digits are dialed to
transmit information to be processed by the computer equipment.
Enhanced Integrated Drive Electronics (EIDE)
An enhanced version of the original standard interface specification (known as IDE) for the hard disk drives that are
associated with personal computers. The original IDE interface is called ANSI Attachment A (ATA). EIDE is also called
ATA-2 or Fast ATA.
Enhanced Private Switched Communications Service (EPSCS)
A private analog telecommunications network that is based on the No. 5 crossbar and 1A ESS switch. An EPSCS can
provide advanced voice services and data services to companies that have many locations. See also
Line Termination (APLT).
ephemeral termination
In H.248 signaling, a termination that is used for an IP connection. For example, a connection between an analog
telephone and an IP telephone is described by an H.248 context with two terminations. These two terminations consist of
a physical termination for the analog telephone that corresponds to a physical port, and an ephemeral termination for the
IP telephone. The ephemeral termination includes additional information that describes the IP side of the call, such as the
codec chosen, the near-end IP addresses and ports, the far-end IP addresses and ports, silence suppression information,
frame rate (samples per IP packet), and so on.
